In a continuous manufacturing process, chlorodifluoromethane (chclf2), initially at 10 bar and 420 k, passes through an adiabatic pressure-reducing valve so that its pressure drops to 0.1 bar (this last pressure is low enough that chclf2 can be considered to be an ideal gas). at these operations conditions, the gas can be represented by a one-term virial equation of state: the following data are available for this gas: in cm3/mol and in j/mol. k what is the temperature of chclf2 exiting the valve?
